  • Combination ultrasound and laser method and apparatus for removing cataract lenses
    Patent number: 6544254
    Abstract: The present invention is a method and apparatus for removing the lens of the eye in which pulsed ultrasound and laser energy are transmitted by means of an optical fiber delivery system to the lens of the eye for therapeutic purposes. The parameters of laser radiation are chosen to optimize the processes of photo-phacoablation and photo-phacodisruption. The vibrational frequencies of ultrasound are selected to optimize sono-fragmentation sono-cavitation. Both laser radiation and ultrasound energy are delivered in effective combinations to maximize the precise removal of cataractous lens material.
